This paper presents capacity planning rules for the control plane of all-optical networks featuring GMPLS and RSVP-TE as
a connection setup protocol. As per RSVP standard, a refresh message mechanism is incorporated to RSVP such that the state is
periodically refreshed on a link per link basis. We provide analytical expressions for the bandwidth and buffer sizes to be provided
such that no flows are torn down due to lack of refresh messages. Our findings show that small buffers (several KBytes) suffice
to sustain the signaling load for as much as 400 RSVP flows per link, with the simplest RSVP refresh mechanism (neither using
link bundling nor acknowledgments). On the other hand, we also find the packet drop probability per link for a given network
topology for the case that the flow survival probability is larger than a given threshold. We provide numerical examples based on
the COST 239 european network topology and real RSVP traffic traces from early-commercial switching equipment. [--]
